Nikka used her fully charged chrome book and drained the battery at a rate of 8 percent per hour while typing a research paper. Marks chromebook was at 28% when he connected it to a power source and recharge the battery at a constant rate of 16% per hour. I need to find to write and solve a System of equation to find when the battery percent will be the same.

the answer is 5/3x+7/5y+7

answer: it is 8

step-by-step explanation:

you know why its 8

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
